2.3 Source #1 AC Input Connections
The connections to be made are the three phases, neutral (if used) and ground cables of input AC Source #1 to the
STS. The main 3-phase cables of input Source #1 are terminated at the Source #1 input busbars. Neutral (if
supplied) and Ground cables are terminated at the Neutral (N) and Ground (GND) busbars respectively. All cables
from Source #1 should be run in a single conduit separately from all other cables (power supply or computer-system
interconnection cables). They should not pass near interference-emitting
equipment or sensitive loads. Complete
wiring instructions for your installation
are provided on the installation drawings supplied with the equipment. See
Figure 1-5 and 1-6, refer to table 1-1 and 1-2 for details.

supplied) and Ground cables are terminated at the Neutral (N) and Ground (GND) busbars respectively. All cables
from Source #2 should be run in a single conduit separately from all other cables (power supply or computer-system
interconnection cables). They should not pass near interference-emitting
equipment or sensitive loads. Complete
wiring instructions for your installation
are provided on the installation drawings supplied with the equipment. See
Figure 1-5 and 1-6, refer to table 1-1 and 1-2 for details.
2.3.2 AC Output Connections
The connections to be made are the three phases, neutral(if used) and ground cables from the load to the STS.
The main 3-phase cables from the load are terminated at the Output busbars. Neutral(if supplied) and Ground
cables are terminated at the Neutral(N) and Ground(GND) busbars respectively. All cables from the load should be
run in a single conduit separately from all other cables(power supply or computer-system interconnection cables).
